Floribunda rose plant named `JACyelsh`

ABSTRACT

A new and distinct variety of rose plant of the floribunda class, having a vigorous, upright habit of growth; resistance to powdery mildew and rust; its dark green, glossy, leathery foliage; continuous blooming during the growing season; and ease of propagation from softwood cuttings.

The present invention relates to a new and distinct variety of roseplant of the floribunda class which was originated by me by crossing twounnamed seedlings.

The primary objective of this breeding was to produce a new rose varietyhaving the bright yellow flowers and healthy, glossy, dark green foliageof the unnamed yellow floribunda seedling female parent combined withthe bright yellow flowers, glossy foliage and tall, vigorous growthhabit of the unnamed yellow shrub male parent. The objective wassubstantially achieved, along with other desirable improvements, asevidenced by the following unique combination of characteristics thatare outstanding in the new variety and that distinguish it from itsparents, as well as from all other varieties of which I am aware:

1. Vigorous, upright habit of growth;

2. Resistance to powdery mildew and rust;

3. Dark green, glossy, leathery foliage;

4. Continuous blooms during the growing season; and

5. Ease of propagation from softwood cuttings.

Asexual reproduction of this new variety by softwood and hardwoodcuttings, as performed at Wasco, Calif., shows that the foregoing andall other characteristics and distinctions come true to form and areestablished and transmitted through succeeding propagations.

The accompanying illustration shows typical specimens of the vegetativegrowth and flowers of this new variety in different stages ofdevelopment, depicted in color as nearly true as it is reasonablypossible to make the same in a color illustration of this character.

The following is a detailed description of my new rose cultivar withcolor descriptions using terminology in accordance with The RoyalHorticultural Society (London) Colour Chart, except where ordinarydictionary significance of color is indicated.
